Porto Rotondo Punta Lada Olbia Wastewater Treatment Plant, Olbia, Sardinia

Porto Rotondo Punta Lada Olbia is a wastewater treatment facility located in the Porto Rotondo area of Olbia, in the Sardinia region of Italy. The plant serves a small community of approximately 1,000 people, reflecting its role in managing local domestic wastewater in a coastal tourist destination. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. With a designed capacity of 1,000 cubic meters per day and a discharge volume of about 198 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment before discharge. The treated effluent is discharged into the coastal waters of the Tyrrhenian Sea, a basin that supports diverse marine life and is important for regional tourism. The advanced treatment helps protect the local marine environment, including nearby beaches and seagrass meadows, from nutrient pollution and other contaminants.

The plant discharges into the Tyrrhenian Sea, part of the Mediterranean Sea, which is a semi-enclosed basin with limited water exchange. The coastal waters near Olbia support seagrass meadows and diverse marine fauna, making them ecologically sensitive. Advanced treatment at this facility helps minimize nutrient loading and protects water quality for recreational use and marine biodiversity.
